IMPROVEMENT IN BRICK-KILNS.

Specication forming part of Letters Patent No. 177,249, dated May 9, '1876; application tiled March 25, 1876.

To all whom it may concern Be it known that I, FRANKLIN F. 'INGER- SOLL, of Browning, in the county of Uarroll and State of Iowa, have invented a new and valuable Improvement in Brick-Kilns; and I do hereby declare that the following isa full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specilication, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation ot' a plan viewA of my brick-kiln; land Fig. 2 is a s ide elevation of the same. Fig. 3 is a transverse vertical sectional view, and Fig. 4 is a detail view, of my brick-kiln.

The nature of my invention consists in the construction and arrangement of a brick-kiln, as will behereinaf'ter more fully set forth.

In the annexed drawing, A represents the oor of the kiln; B B are the side walls, and

vD D the end walls, the side walls being supported by the usual frame-Work E. The root' of the kiln is composed of alternate stationary and removable sections G and C', preferably' made of metal. The stationary sections C are built in or fastened to the Walls in any suitable manner, while the sections C are made movable, so as to be partially or wholly removed, or entirelyr closed, as may be desired, for the removal of water, smoke, or tol assist in controlling the draft. These maovable sec-4 tions are fastened to the stationary sections by thumb-screws or other convenient means. Along the front of the kiln are a series of furnaces, G G, which are made flaring inward, so as to make them wider next to the material to be burned. Within the kiln the brick are laid so as to forni an arch, H, the entirelength of the front of the kiln, and transverse arches I I extending from this arch to the back wall of the kiln'in front of each furnace and mid way between the furnaces. These arches I I communicate with fines a a controlled by dampers b b outside of the kiln, and connecting with a horizontal liue,'J,1eading to the chimney K. l

By this construction the iire can be more perfectly controlled and distributed, and the inside ot' the kiln is left entirely free of dampers.

What I claim as new, and desire to secure by Letters Patent, is

In a brick-kiln, the top or roof composed of alternate stationary sections C' built into the sides of the kiln, and movable or adjustable sections G, and fastened thereto by thumbscrews or their equivalents, as and for the purpose set forth.

Y In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
